If the standard model of particle interactions is extended to include a neutral SU(2)(N) gauge factor, with SU(3)(C) x SU(2)(L) x U(1)(Y) x SU(2)(N) embedded in E(6) or [SU(3)](3), a conserved generalized R parity may appear. As a result, apart from the recent postulate of a separate non-Abelian gauge factor in the hidden sector, we have the first example of a possible dark-matter candidate X(1) which is a non-Abelian vector boson coming from a known unified model. Using current data, its mass is predicted to be less than about 1 TeV. The associated Z' of this model, as well as some signatures of the Higgs sector, should then be observable at the LHC (Large Hadron Collider).
